Bioparticle measuring method

The present disclosure relates to a bioparticle measuring method including forming on a solid phase a complex of a sample containing a bioparticle sampled from a specimen, a capturer containing a tag which binds to the solid phase and capable of binding to the bioparticle, and a detector capable of binding to the bioparticle and containing a labeled substance. A part or the whole of the complex may be dissociated from the solid phase to prepare a measurement sample containing a part or the whole of the complex not fixed on the solid phase, and signals from the measurement sample may be detected by a particle analyzer.

LIPID COMPOSITIONS COMPRISING PEPTIDE-LIPID CONJUGATES

A lipid composition containing a nucleic acid, wherein the lipid composition comprises a peptide-lipid conjugate, is provided. The peptide of the peptide-lipid conjugates can be from 4 to 52 amino acids in length. Methods of using the lipid composition in the in vivo delivery of nucleic acids are further provided.

Pluripotent stem cell assay

The invention relates to a method for detecting residual, undifferentiated pluripotent stem cells (PSCs) in a culture of cells differentiated from PSCs, the method comprising: culturing the cells on a substrate coated with laminin-521 and E-cadherin in a medium comprising a ROCK inhibitor; quantitating in the cultured cells expression of a marker of residual, undifferentiated PSCs; and comparing the marker expression in the cultured cells with the marker expression in a reference culture of cells comprising a known proportion of PSCs, wherein lower marker expression in the culture of cells than marker expression in the reference culture of cells indicates absence of residual, undifferentiated PSCs in the cultured cells or presence of residual, undifferentiated PSCs in the cultured cells at a proportion lower than the known proportion of PSCs in the reference culture of cells. The invention also relates to a method for manufacturing a therapeutic composition and a method for treating or preventing a condition in a subject.

Bioparticle measuring method

The present disclosure relates to a bioparticle measuring method including detecting a signal from a first measurement sample and a signal from a second measurement sample, wherein the first measurement sample is prepared by mixing a first sample containing a bioparticle sampled from a specimen with a detector capable of binding to the bioparticle and containing a labeled substance, in the presence of an inhibitor capable of binding to the bioparticle and containing none of the labeled substance. The second measurement sample is prepared by mixing a second sample sampled from the same specimen independently from the first sample with the detector, under a condition that the inhibitor is substantially absent. A measurement result is then calculated from the detected signals from the first and second measurement samples.
